context_page_description: Mesolite is a tectosilicate mineral with formula Na₂Ca₂(Al₂Si₃O₁₀)₃·8H₂O. It is a member of the zeolite group and is closely related to natrolite which it also resembles in appearance.
  Mesolite crystallizes in the orthorhombic system and typically forms fibrous, acicular prismatic crystals or masses. Radiating sprays of needlelike crystals are not uncommon. It is vitreous in luster and clear to white in color. It has a Mohs hardness of 5 to 5.5 and a low specific gravity of 2.2 to 2.4. The refractive indices are nα=1.505 nβ=1.505 nγ=1.506.
